1.  final class ConcurrentMap[K, V] extends AnyVal

   Wrapper over java.util.concurrent.ConcurrentHashMap.

2.  final class ConcurrentSet[A] extends AnyVal

   A ConcurrentSet is a Set wrapper over java.util.concurrent.ConcurrentHashMap.

3.  final class CountdownLatch extends AnyRef

   A synchronization aid that allows one or more fibers to wait until a set of operations being performed in other fibers completes.

   A synchronization aid that allows one or more fibers to wait until a set of operations being performed in other fibers completes.

   A CountDownLatch is initialized with a given count. The await method block until the current count reaches zero due to invocations of the countDown method, after which all waiting fibers are released and any subsequent invocations of await return immediately. This is a one-shot phenomenon -- the count cannot be reset. If you need a version that resets the count, consider using a CyclicBarrier.

   A CountDownLatch is a versatile synchronization tool and can be used for a number of purposes. A CountDownLatch initialized with a count of one serves as a simple on/off latch, or gate: all fibers invoking await wait at the gate until it is opened by a fiber invoking countDown. A CountDownLatch initialized to N can be used to make one fiber wait until N fibers have completed some action, or some action has been completed N times.

   A useful property of a CountDownLatch is that it doesn't require that fibers calling countDown wait for the count to reach zero before proceeding, it simply prevents any fiber from proceeding past an await until all fibers could pass.

4.  final class CyclicBarrier extends AnyRef

   A synchronization aid that allows a set of fibers to all wait for each other to reach a common barrier point.

   A synchronization aid that allows a set of fibers to all wait for each other to reach a common barrier point.

   CyclicBarriers are useful in programs involving a fixed sized party of fibers that must occasionally wait for each other. The barrier is called cyclic because it can be re-used after the waiting fibers are released.

   A CyclicBarrier supports an optional action command that is run once per barrier point, after the last fiber in the party arrives, but before any fibers are released. This barrier action is useful for updating shared-state before any of the parties continue.
